No! During ALT* leave it alone it's too late. It's a capture phase where the rate of CLB or DES is flattening out. Even VS0 is not instant but gradual. You are likely to mess it up. When in a hurry people have played piano on the FCU. Pressing EXPED instead off ARM(ILS) then not knowing how to come out tried to press EXPED again but this time pressed ATHR causing THR LK, then trying to remove THR LK pressed ID on thrust levers driving thrust to CLB and busting speed and also causing GPWS terrain.

TCAS does it's job well don't do anything last minute.
